I am going crazy trying to get this iMac up and running! Hopefully, someone can help. I got a iMac, G3, 233mHz, tray loading machine. I replaced the hard drive with a 120GB Western Digital drive and replaced the battery.

I followed all the proceedures including: zapping the P-RAM (multiple times), initialized the drive (7.5GB first partition), went into the firmware and reset the nvram, reset the CUDA switch.

I was able to load OS 9.2.1 successfully. I chose the proper start up disk, and restarted. All I got was the flashing ? and the OS icon. The system folder is blessed. So I put the OS cd in waited until the icon stopped blinking, ejected the cd. The screen went gray, then another flashing disk came up. If I hold down the power button for a few seconds, the happy mac comes up, and it starts. Why is it doing this, and what can I do to rectify the situation. I am giving this machine to my uncle and his family that I have convinced to "switch". Please help. Thanks!

Have you tried starting up holding down the option key?

Yes and it still doesn't do anything. Just the flashing ?.

Oh sorry, I have had a similar experience and I was able to boot up that way and then reselect the startup disk while booted from the HD - don't know why it worked for me and I'm not sure what else to suggest.

Are you able to run disk utitlity from the CD? - does it report any problems?

I am able to, do you think it could be a jumper issue?

Possibly - I am not exactly sure what you should set it to but I would try master first then cable select. I know that model has 2 IDE busses unlike the later models....

Make sure you've installed the OS 9 drivers on your hard drive.
This can be done via drive setup, have a look in the menu's.

Thanks to all that helped, I got it up and running last night! It was the jumper on the back of the drive causing the issue.

My experience with these machines is to take all jumpers off of the hard drive- then they will start up from a blessed folder on the drive. Make sure that you have installed the OS on the first 8GB- you will need to partition the drive to do this. It may start up now but information "moves" around on a drive. If any of the OS gets beyond the first 8GB, you will be getting a call from your uncle wondering why it won't start up.
